Azido{4,4′-dibromo-2,2′-[ethane-1,2-diylbis(nitrilomethanylylidene)]diphenolato-κ4O,N,N′,O′}manganese(III) Yingxia Liu S1. Comment In the past decade there has been much interest in the magneto-chemistry of manganese because of its special magnetic properties. As is well known, manganese (III) Schiff base complexes display interesting structural, magnetic properties and electronic effects which rank it among the most appealing candidates as a building paramagnetic motif for multidimensional expanded structures. The variation of in-plane chelating and axial sites often leads to a change in the spin state of the metal ions: high-spin, low-spin or spin-crossover state. The nature and the tuning of magnetic interactions between metal centers are crucial points in the conception of molecular-based magnetic materials. The molecular structure of the title compound is shown in Figure 1. The MnIII ion is involved in a distorted squarepyramidal arrangement by a N3O2 unit, in which the four basal sites are occupied by two N atoms and two O atoms from the Schiff base ligand, and the apical position is occupied by the N atom of an azido ligand. The bond distances are comparable to those found in related structures (Lu, et al., 2006; Mikuriya, et al., 1992; Li, et al., 1997; Wang, et al., 2008). The MnIII ion lies above the basal plane formed by N2O2 unit by 0.228 (1) Å. The short intermolecular distance of Mn···Ophenolate 2.667 (2) Å indicates that there exists weak interaction between the two complexes related by inversion centers in the crystal (Figure 2). The phenyl groups of the Schiff base are involved in an offset face-to-face π-π intercomplexes stacking interaction (ring centroid separation Cg···Cgi, 3.598 (2) Å) [symmetry code: 2 - x,1 - y,1 - z]. S2. Experimental This compound was synthesized by mixing a solution of Schiff base (2,2′-((1E,1′E)-(ethane-1,2-diylbis(azanylylidene)) bis(methanylylidene))bis(4-bromophenol)) (0.5 mmol) in methanol (5 ml) with a solution of MnCl2.4H2O (0.5 mmol) in methanol (5 ml), followed by the dropwise addition of an aqueous solution NaN3(0.6 mmol, 2 mL) without stirring. The black mixture was allowed to stand for several days until good quality black block crystals of the compound were obtained in a yield of 68.3%. S3. Refinement All the H atoms bonded to the C atoms were placed using the HFIX commands in SHELXL97 (Sheldrick, 2008) with C— H distances of 0.93 and 0.97 Å, respectively, and were allowed for as riding atoms with Uiso(H) = 1.2Ueq(C)..

Special details Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
